In this paper, starting from a robust statistics (RS) adaptive approach presented in a previous work entitled the combined NLMS-Sign (CNLMS-S) adaptive filter, an automatic combination technique with similar performances is proposed. Thus, in order to obtain better performances in acoustic echo cancellation (AEC) setups than with the normalized least-mean square (NLMS) algorithm, in the CNLMS-S...

Actively phase-locked heterodyne-detected fifth-order nonresonant Raman scattering from room temperature CS2 has been measured. The experimental signals have similar magnitudes, shapes, and sign changes as calculated responses obtained via molecular dynamics simulations [S. Saito and I. Ohmine, Phys. Rev. Lett. 88, 207401 (2002)]. The measured signals contain sign changes that appear to be asso...

A sign pattern matrix is a matrix whose entries are from the set {+,−, 0}. The minimum rank of a sign pattern matrix A is the minimum of the ranks of the real matrices whose entries have signs equal to the corresponding entries of A. It is shown in this paper that for any m×n sign pattern A with minimum rank n− 2, rational realization of the minimum rank is possible. This is done using a new ap...

Nowadays, air pollution is one of the major problems in developed and developing countries. In recent years, effects of air pollution on neuroinflammatory diseases such as Alzheimer disease and Parkinson disease have been studied. Researches on polluted cities citizens indicate increasing in central nervous system (CNS) inflammatory factors in comparison with clean cities; also air pollution ex...

potentiality, Quality is closer to a blend of Firstness and Thirdness, than to pure Firstness. Such a treatment seems to be compatible with Peirce’s categorical scheme, since, as Potter (1997: 94) stresses, the categorical structure which Peirce uses is ‘highly subtle and complex, admitting of various combinations’. For Murphey, there is a transition from the notion of meaning as a qualitative ...

We assessed whether sign-tracking developed along with goal-tracking in a Pavlovian drug discrimination task. Rats had nicotine sessions intermixed with saline sessions. For nicotine sessions, 15-s illumination of a light near (Experiment 1) or far (Experiment 2) from the dipper receptacle was followed by sucrose. Saline sessions were similar to nicotine sessions except sucrose was withheld. Re...

We comment on Linde’s claim that one should change the sign in the action for a Euclidean instanton in quantum cosmology, resulting in the formula P ∼ e−|S| for the probability of various classical universes. There are serious problems with doing so. First, the action for perturbations about the classical solution has the wrong sign and such perturbations are therefore unsuppressed. Second, wit...

Although Surgical Implant Generation Network (SIGN) has made continuous progress toward achieving its mission over the last 10 years, significant work remains. We envision 3 main areas for future growth: research, education, and technologic development. There is a dearth of information regarding the incidence of musculoskeletal injury, types of treatment used, and resultant outcomes in developi...

In this paper we prove an asymptotically tight bound (asymptotic with respect to the number of polynomials for fixed degrees and number of variables) on the number of connected components of the realizations of all realizable sign conditions of a family of real polynomials. More precisely, we prove that the number of connected components of the realizations of all realizable sign conditions of ...
